The first fully-automatic gold refining system with integrated nitric and hydrochloric acid recovery
The new Puras® gold refining system from Koras® is able to refine all types of precious metal alloys in a fully automatic process without the release of acidic gases and with the recovery of nitric and hydrochloric acid.
The system consists of glass reactors with a heating mantle with stirrer, gold precipitation container, and special fume scrubbers for NOx and Cl2 gases. These special fume scrubbers can be used to recover nitric acid (up to 50%) from NOx gases and hydrochloric acids (up to 30%) from HCl /Cl2 to enable reuse for the dissolving process. The complete fully automatic process guiding and monitoring is made using a touch display.
